The Variable Frequency Drive (VFD) market is positioned for growth with some reports predicting a market value greater than $20 billion by 2021. What's driving this growth? Advantages to using VFD such as tighter process control and cost savings achieved through improved efficiency, reduced energy usage, and decreased maintenance. While controllers and motors combine as the two primary components to VFD, there is one additional component that is often overlooked and yet it is key to achieving the above-outlined benefits: the cable.
A Variable Frequency Drive (VFD) is a type of controller that varies the frequency of the signal and voltage to control motor speed. Other common names for VFD include variable speed drive, adjustable speed drive, constant torque drive, inverter drive, and pulse width modulation (PWM) drive.
Engineer and inventor, Nikola Tesla, contributed tremendously to the development of the alternating current (AC) electrical system and the rotating magnetic field. Determined to carry out his forward-thinking vision of AC, Tesla was an inspiration across many industries in the name of science who dared to challenge other technological advancements of his time, such as Thomas Edison's direct current (DC) electrical powerhouses.
